Transformer uses ExoPlayer for reading input. Apps using Transformer
do not need to know this. So, PlaybackExceptions are converted to
TransformationExceptions with the same message, cause and error code.

The corresponding IO error codes are copied from PlaybackException.

We check the fraction of the available duration we have already
buffered for live streams to see if we can increase the quality.
This fraction compares against the overall available media duration
at the time of the track selection, which by definition can't include
one of the availabe chunks (as this is the one we want to load next).

That means, for example, that for a reasonable live offset of 3 segments
we can at most reach a fraction of 0.66, which is less than our default
threshold of 0.75, meaning we can never switch up.

By subtracting one chunk duration from the available duration, we make
this comparison fair again and allow all live streams (regardless of
live offset) to reach up to 100% buffered data (which is above our
default value of 75%), so that they can increase the quality.

Before the introduction of the MediaCodecAdapter, users could get
access directly to the MediaCodec instance from
MediaCodecRenderer.getCodec() and then retrieve the codec metrics.

This change exposes MediaCodec.getMetrics() on the MediaCodecAdapter.

This change adds a delegate class that loads and forwards calls
to a Spatializer with reflection, so that we can use the Spatializer
API before we update the compile SDK target to 32.

The Robolectric implementation of HttpURLConnection forwards to the JRE
implementation [1], which behaves differently to the Android one
available on devices and emulators. For these tests to be a realistic
test of the HTTP stack used in real playbacks we can't use Robolectric.

UnsupportedEglVersionException() is only used once, and seems a bit too
specific for Transformer. Also, it's possible for eglCreateContext to fail for
other reasons besides lack of support, so it wasn't always accurate when
thrown.

It is possible for devices not to support EGL version 2.0 though, per
https://source.android.com/devices/graphics/implement-opengl-es, which doesn't
specify the EGL version that must be supported.

tl;dr:
In the previous transformer, the transcoding flow is

- If a the GL's input surface (from decoder) does not have data, wait 10ms
 (DO_SOME_WORK)
- Else, make the decoder render **ONE** frame to the GL's input surface
  - Wait at least 10ms, until the frame's texture is available
  - Then process the texture

The process is quite slow, so in the new version, we do:
- If a the GL's input surface (from decoder) does not have data, wait 10ms
 (DO_SOME_WORK) **same**
- Else, make the decoder render **as many frames** to the GL's input surface
  - Process **as many** available textures in this DO_SOME_WORK cycle

Make audio track min buffer size configurable.

Move the code in its own class as DefaultAudioTrack
is getting very big. It also help for testability.

The new class is easily configurable and highly tested.
Manual test was used to catch any regression.

The input rotation is used to rotate the video during decoding, the
video is rotated so that it is in landscape orientation before encoding
and a rotation is added to the output format where necessary so that
the output video has the same orientation as the input.

For DASH manifests, we merge min/max live latency values from various
sources and they may not be consistent with each other. To ensure we
use a sensible configuration in all cases, we can add more correctness
checks:
 1. Limit the min/max values to fall into the available live window.
 2. Ensure that maxLatency >= minLatency in all cases.
